摘  要:
用试验方法研究了站立状态下鸡的动态特性。测量了随机激励下鸡的背、胸和腿3处的频率响应函数,得到了鸡的二阶共振频率。试验结果表明,目前国内通用的网状鸡舍的共振频率和鸡本身的共振频率范围(13~14 Hz)相同,这应引起有关设计人员的注意。

摘  要:
The dynamic characteristics of chicken in standing posture are studied experimen- tally.Frequency response functions at the back,chest and leg of a chicken are measured, from which two resonant frequency is obtained.Based on the measurement,it is pointed out that the resonant frequency domain of net-shape chicken house which is widely used at pre- sent is nearly equal to that of chicken body.
